SELF-LUBRICATING TROLLEY-WHEEL.

Specification of Letters Patent.

Patented Aug. 7, 1906.

Application filed March 8, 1906. Serial N 0. 504,935.

To all, whom, it may concern:

Be it known that I, THEOPIHL BEDNARO- WICZ, a citizen of the UnitedStates, residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements inSelf-Lubricating Trolley-Wheels; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in self-lubricatingtrolley-wheels.

The object of theinvention is to provide a wheel of this character inwhich lubricating material may be stored, means being provided wherebysaid lubricating material will be properly fed to the axle or journal ofthe wheel, thus providing for the lubricating of the same.

With the above and other objects in view the invention consists ofcertain novel features of construction, combination, and arrangement ofparts, as will be hereinafter de- 2 5 scribed and claimed.

In the accompanying drawings, Figure 1 is a vertical sectional view of atrolley-wheel constructed in accordance with the invention. Fig. 2 is asimilar view taken at right 0 angles to Fig. 1, and Fig. 3 is adetail'sectional view of the same.

Referring more particularly to the drawings, 1 denotes the wheel, whichmay be of the ordinary or any desired construction provided on its outeredge or periphery with wire-engaging grooves 2 and outwardly-flaringflanges 3. The body of the wheel is preferably formed hollow and isprovided with a series of radially-disposed partitions 4, of

40 which there may be any desired number, the wheel being here shown asprovided with four partitions arranged diametrically opposite to eachother, thus dividing the hollow body of the wheel into four chambers orpockets 5, which communicate with the bushing 6 through openings formedin the hub 7 of the wheel.

In the partitions 1 are formed passages 8, whereby communication will beaiforded between the compartments or pockets 5 to facilitate thecirculation of the lubricating material therethrough. The passages 8 maybe arranged in any suitable position in the partitions, but arepreferably formed in the upper corners of the same, as shown.

Formed in one side of the rim of the wheel is a filling opening orpassage 9, which communicates with one of the compartments or pockets 5and is normally closed by a screwplug 10. Arranged in the hub 7 of thewheel is a bushing 12, said bushing being provided in one side with alongitudinally-disposed slot 13 and in its opposite side with acentrally-disposed hole 1 1. The slot 13 is for the purpose of admittingthe lubricant from the compartments or pockets 5 to the journal of thewheel in the proper quantities to lubricate the same. The hole 14 is forthe purpose of providing a vent to permit the escape of air from betweenthe journal and the bushing, thus facilitating the entrance of the oilor other lubricating material through the slot 13 to the journal.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without. requiring a more extendedexplanation.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The herein-described self-lubricating trolley-wheel consisting of ahollow body por tion, radially-disposed partitions arranged therein toform pockets for holding lubricatmaterial, said partitions havingcommunicating openings at their outer corners, a hub formed on saidwheel, a bushing disposed within said hub, said bushing having in one ofits sides a longitudinally-disposed feed-slot and in its opposite side avent-opening, a filling-opening formed in one side of said wheel andcommunicating with one of said pockets, and a plug to close saidopening, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- IIBSSQS.
